What is the equation of this line of best fit in slope intercept form

Option B:

Equation of the line of best fit in slope-intercept form is .

Solution:

Take two points on the line (0, 1) and (4, 3).

So, .

Slope of the line:

y-intercept means the point which crosses at y-axis.

Here the point on the y-axis is (0, 1).

y-intercept (b) = 1

Slope-intercept form:

y = mx + b

Equation of the line of best fit in slope-intercept form is .

Option B is the correct answer.

the ratio of balloons to tables is 5: 2 and the constant variation is 5.

the equation is y=5x
